About Watermark PDF
Position custom diagonal text, stamps, or vector logos. Unlike traditional cloud conversion services, FileLab executes computations directly in your browser using modern WebAssembly (WASM) and HTML5 Canvas APIs. Your private documents, images, and media never leave your device or touch an external server.
Files are converted in browser RAM and destroyed immediately upon task completion.
